% GUI_MULTI_N_BACK M-file for GUI_Multi_N_Back.fig
%      GUI_MULTI_N_BACK, by itself, creates a new GUI_MULTI_N_BACK or raises the existing
%      singleton*.
%
%      H = GUI_MULTI_N_BACK returns the handle to a new GUI_MULTI_N_BACK or the handle to
%      the existing singleton*.
%
%      GUI_MULTI_N_BACK('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in GUI_MULTI_N_BACK.M with the given input arguments.
%
%      GUI_MULTI_N_BACK('Property','Value',...) creates a new GUI_MULTI_N_BACK or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before GUI_Multi_N_Back_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to GUI_Multi_N_Back_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
